Description

本発明は、足場に関し、特に詳しくは、建物と足場の隙間を塞ぐための屋根構造に関するものである。   The present invention relates to a scaffold, and more particularly to a roof structure for closing a gap between a building and a scaffold.

従来から、建物と足場の間に生じる隙間上部を覆うような屋根構造に関する発明は多数存在する。   Conventionally, there are many inventions related to a roof structure that covers an upper portion of a gap generated between a building and a scaffold.

例えば、特許文献1に記載される枠組み足場用屋根は、足場の最上段に設置して使用されるものである。   For example, the roof for a framework scaffold described in Patent Document 1 is used by being installed on the uppermost stage of the scaffold.

また、特許文献2においては、建物に近い側の足場支柱と建物から離れた足場支柱の両方に架設することによって屋根を傾斜して設置する足場用屋根が開示されている。   Moreover, in patent document 2, the roof for scaffolding which inclines and installs a roof by constructing in both the scaffolding support | pillar of the side close | similar to a building, and the scaffolding support | pillar distant from a building is disclosed.

一方で、近年の足場においては、図8に示したような所謂クサビ式足場1が利用されるケースが増えている。クサビ式足場1は、支柱2の高さ方向一定間隔毎に設けられる受け部(所謂こぶ)3に対して、踏み板や手摺等の水平部材4の端部に設けられるクサビ5を打ち込んで緊結し、足場を組み上げるといいうものである。   On the other hand, in recent years, the so-called wedge type scaffold 1 as shown in FIG. 8 is increasingly used. The wedge-shaped scaffold 1 is fastened with a wedge 5 provided at the end of a horizontal member 4 such as a footboard or a handrail with respect to a receiving portion (so-called hump) 3 provided at regular intervals in the height direction of the column 2. Is to build a scaffold.

しかしながら、特許文献1に記載の足場用屋根は、足場の最上段にしか設置できないという問題点があった。また、特許文献2に記載の足場用屋根は、建物に近い側の足場支柱と建物から離れた側の足場支柱の両方に屋根を固定するためのブラケットを取り付けるスペースが必要となり、更に、そのスペースの位置は屋根の傾斜によって制限を受けるため現実的には取り付ける場所の確保が困難という問題があった。   However, the scaffold roof described in Patent Document 1 has a problem that it can be installed only on the uppermost stage of the scaffold. Moreover, the roof for scaffolds described in Patent Document 2 requires a space for attaching a bracket for fixing the roof to both the scaffolding pillar on the side close to the building and the scaffolding pillar on the side away from the building. Since the position of is limited by the slope of the roof, there is a problem that it is difficult to secure a place to install it.

発明者はこういった問題点を鑑み、また、現在足場として利用されることの多い「クサビ式足場」の構造を最大限に利用することで、上記問題点が一気に解決できることに思い至ったのである。   In view of these problems, the inventor has realized that the above problems can be solved at once by making full use of the structure of a “wedge type scaffold” that is often used as a scaffold at present. is there.

本発明は、こういった問題点を解決するべくなされたものであって、足場の最上段に限らず容易に設置でき、更には取り外しも容易なクサビ式足場用屋根構造を提供する事をその課題としている。   The present invention has been made to solve these problems, and is intended to provide a wedge-shaped scaffold roof structure that can be easily installed without being limited to the uppermost stage of the scaffold, and can be easily removed. It is an issue.

上記課題を解決するべく、本願発明は、クサビ式足場を構成する縦支柱に設けられる受け部に嵌入するクサビ部と、当該クサビ部を前記受け部に嵌入すると水平方向若しくは斜め下方向若しくは斜め上方向に延在する骨部と、当該骨部の基端近傍及び先端近傍の両側面に設けられた締結部と、を備えるフレーム部材と、四隅に穴を備えた矩形のシート部材と、を備え、少なくとも2つの前記フレーム部材を前記クサビ式足場における使用されていない受け部に嵌入させ、前記シート部材の穴と前記フレーム部材の締結部とを紐等の締結部材で締結することによって、前記フレーム部材同士を前記シート部材で繋いだことを特徴とする。   In order to solve the above problems, the present invention provides a wedge portion that fits into a receiving portion provided on a vertical support that constitutes a wedge type scaffold, and a horizontal direction, an obliquely downward direction, or an obliquely upward shape when the wedge portion is fitted into the receiving portion. A frame member including a bone portion extending in a direction, and fastening portions provided on both side surfaces near the proximal end and the distal end of the bone portion, and a rectangular sheet member including holes at four corners. The frame member is inserted into a receiving portion that is not used in the wedge type scaffold, and the hole of the seat member and the fastening portion of the frame member are fastened with a fastening member such as a string. The members are connected by the sheet member.

このような構成を採用したことによって、足場の最上段に限らず容易に設置でき、更には取り外しも容易なクサビ式足場用屋根構造を提供する事を可能としているのである。即ち、縦支柱には使用されていない受け部(こぶ)が多数存在するため、その使用されていない受け部を利用して屋根構造を取り付けるのである。特にクサビ式足場を建物の周りに組み付けた際には、建物から見て支柱の左右方向に配置された受け部は足場の組み付けに使用されているケースが多いものの、建物側に向かって配置された受け部は使用されないままとなっているケースが多い。この使用されていない受け部にクサビを打ち込むように屋根部材のフレーム部を複数取り付け、更にこれら複数のフレーム部材同士を矩形のシート部材で繋いで屋根を構成するのである。   By adopting such a structure, it is possible to provide a roof structure for a wedge type scaffold that can be easily installed not only at the uppermost stage of the scaffold, but also can be easily removed. That is, since there are a large number of receiving portions (humps) that are not used in the vertical struts, the roof structure is attached using the unused receiving portions. In particular, when the wedge type scaffolding is assembled around the building, the receiving parts arranged in the left and right direction of the column as viewed from the building are often used for assembling the scaffolding, but are arranged toward the building side. In many cases, the receiving part remains unused. A plurality of frame parts of the roof member are attached so that wedges are driven into the unused receiving part, and the plurality of frame members are connected by a rectangular sheet member to constitute a roof.

足場の組み付けと同様に、クサビを打ち込むようにしてフレーム部材を取り付けるので、取り付け作業は極めて容易であるし、取り外しも容易となる。更に、空いている受け部に自由に取り付けできるため、最上段に限らず、中段部や下段部においても問題なく設置可能である。場合によっては、低い位置から高い位位置に向かって斜め方向に屋根を設置することも可能となる。   Similar to the assembly of the scaffold, the frame member is attached by driving in the wedge, so that the attachment work is extremely easy and the attachment is easy. Furthermore, since it can be freely attached to a vacant receiving part, it can be installed without any problems not only in the uppermost stage but also in the middle or lower part. In some cases, it is possible to install a roof in an oblique direction from a low position to a high position.

また、前記骨部を、基端側を中心として、前記先端部が上下に変位するように回動可能に支持すると共に、所望の角度で固定することができるようにしてもよい。   Further, the bone portion may be rotatably supported so that the distal end portion is displaced up and down around the proximal end side, and may be fixed at a desired angle.

このように構成すれば、状況に合わせて屋根の角度を所望の角度に調整することができる。更に、好天時には、屋根を上部に解放することも可能なため、屋根を取り付けた後であっても、積極的に光を取り入れることも可能となる。   If comprised in this way, the angle of a roof can be adjusted to a desired angle according to a condition. Furthermore, since it is possible to release the roof to the upper part in good weather, it is possible to actively take in light even after the roof is attached.

また、前記フレーム部材の右側に配置される前記シート部材は、当該フレーム部材の左側面に設けられた前記締結部と締結され、前記フレーム部材の左側に配置される前記シート部材は、当該フレーム部材の右側面に設けられた前記締結部と締結されることを特徴とする。   Further, the sheet member disposed on the right side of the frame member is fastened to the fastening portion provided on the left side surface of the frame member, and the sheet member disposed on the left side of the frame member is the frame member. It is fastened with the said fastening part provided in the right side surface of this.

このようにフレーム部材とシート部材とを締結することによって、極めて簡易な構成ではあるものの、シート部材同士の間に隙間が生じることを防止できるので、雨が隙間から漏れ難くなっている。   By fastening the frame member and the sheet member in this manner, although it is an extremely simple configuration, it is possible to prevent a gap from being generated between the sheet members, so that it is difficult for rain to leak from the gap.

本発明を適用することで、足場の最上段に限らず容易に設置でき、更には取り外しも容易な足場用屋根構造を提供することができる。   By applying the present invention, it is possible to provide a roof structure for a scaffold that can be easily installed without being limited to the uppermost stage of the scaffold and that can be easily removed.

<Configuration of roof structure for wedge type scaffolding>
As shown in FIG. 1, the wedge-shaped scaffolding roof structure 100 shown as an example of the embodiment of the present invention is installed by using unused receiving portions 3 of the vertical struts 2 constituting the wedge-shaped scaffold 1. Is done.

クサビ式足場屋根構造100は、少なくとも2つのフレーム部材110と、そのフレーム部材110同士を繋ぐように取り付けられる矩形のシート部材120を主たる構成要素として成り立っている。   The wedge-shaped scaffolding roof structure 100 is composed mainly of at least two frame members 110 and a rectangular sheet member 120 attached so as to connect the frame members 110 to each other.

フレーム部材は、図2に示しているように、縦支柱2の受け部3に嵌入されるクサビ部111と、このクサビ部111を縦支柱2の受け部3に嵌入させると水平方向若しくは斜め下方向若しくは斜め上方向に延在する骨部112と、この骨部112の基端近傍に設けられた基端側締結部115及び先端近傍の両側面に設けられた先端側締結部116とを備えている。また、骨部112は棒状部材113と当該棒状部材113をクサビ部111に対して回動可能に支持すると共に、所定の位置で固定できる基台部114よりなる。また、この基台部114には、回動方向に段階的に設けられた複数のピン孔117と、当該ピン孔117に通すための固定ピン118が備わっている。また、基台部114の内側に位置する棒状部材113側にも固定ピン118を挿通させるための穴が備わっており(図面上現れていない。)、当該穴に、固定ピン118を所望位置のピン孔117を介して挿通させることによって、棒状部材113が所望の角度で固定される構成とされている。   As shown in FIG. 2, the frame member includes a wedge portion 111 that is fitted into the receiving portion 3 of the vertical column 2, and a horizontal or diagonally downward position when the wedge portion 111 is fitted into the receiving portion 3 of the vertical column 2. A bone portion 112 extending in a direction or obliquely upward, a proximal-side fastening portion 115 provided in the vicinity of the proximal end of the bone portion 112, and a distal-side fastening portion 116 provided on both side surfaces in the vicinity of the distal end. ing. Further, the bone portion 112 includes a rod-shaped member 113 and a base portion 114 that can rotatably support the rod-shaped member 113 with respect to the wedge portion 111 and can be fixed at a predetermined position. Further, the base portion 114 is provided with a plurality of pin holes 117 provided in a stepwise manner in the rotation direction, and a fixing pin 118 for passing through the pin hole 117. Further, a hole for inserting the fixing pin 118 is also provided on the side of the rod-shaped member 113 located inside the base portion 114 (not shown in the drawing), and the fixing pin 118 is placed at a desired position in the hole.

〈クサビ式足場用屋根構造の使用方法〉
クサビ式足場用屋根構造100の使用方法は極めて簡易である。組み上げたクサビ式足場1の縦支柱2の使用されていない受け部3にフレーム部材111(のクサビ部111)をハンマー等で複数打ち込み、その後それらを繋ぐようにシート部材を取り付けるのみである。なお、棒状部材113の角度は、棒状部材113の角度を適宜位置決めした上で、固定ピン118をピン孔117を介して差し込むことによって調整する。
<How to use the wedge structure roof structure>
The method of using the wedge structure roof structure 100 is very simple. A plurality of frame members 111 (wedge portions 111) are driven with a hammer or the like into the unused receiving portion 3 of the vertical strut 2 of the assembled wedge-type scaffold 1 and then a sheet member is simply attached so as to connect them. The angle of the rod-shaped member 113 is adjusted by inserting the fixing pin 118 through the pin hole 117 after appropriately positioning the angle of the rod-shaped member 113.

このとき、シート部材120の締結は、例えば図4に示したように行うのが望ましい。図4は、棒状部材113の先端側から棒状部材113とシート部材120を表した図面である。図示しているように、棒状部材113の右側に配置されるシート部材120は、当該棒状部材113の左側面に設けられた締結部116aと締結される。一方で、棒状部材113の左側に配置されるシート部材130は、当該棒状部材113の右側面に設けられた締結部116bと締結される。なお、棒状部材113の基端側においても同様に締結される。即ち、図示の通り、隣り合うシート部材120が、棒状部材113の太さ分だけ重なり合うように締結されている。なお、図示していないが、シート部材120に備わる穴122と締結部116とは紐やタイラップ等の締結部材によって締結されて固定される。また、図4では、シート部材120が棒状部材113を境に順次上下となるような締結となっているが、図5に示しているように、シート部材120の一端側が上で他端側が下となるような繰り返し(例えるなら瓦屋根の瓦の並びの繰り返し)で締結することも可能である。   At this time, it is desirable to fasten the sheet member 120 as shown in FIG. FIG. 4 is a view showing the rod-shaped member 113 and the sheet member 120 from the distal end side of the rod-shaped member 113. As illustrated, the sheet member 120 disposed on the right side of the rod-shaped member 113 is fastened to a fastening portion 116 a provided on the left side surface of the rod-shaped member 113. On the other hand, the sheet member 130 disposed on the left side of the rod-shaped member 113 is fastened with a fastening portion 116 b provided on the right side surface of the rod-shaped member 113. It is also fastened similarly on the base end side of the rod-shaped member 113. That is, as illustrated, adjacent sheet members 120 are fastened so as to overlap by the thickness of the rod-shaped member 113. Although not shown, the hole 122 provided in the sheet member 120 and the fastening portion 116 are fastened and fixed by a fastening member such as a string or a tie wrap. In FIG. 4, the sheet member 120 is tightened up and down sequentially with the rod-shaped member 113 as a boundary. However, as shown in FIG. 5, one end side of the sheet member 120 is up and the other end side is down. It is also possible to conclude by repeating such that (for example, repeating the arrangement of tile roof tiles).

このような手順により、例えば図6に示しているように、クサビ式足場1に対して足場用屋根構造100が設置されることとなる。図示のように、地面に設置される足場に取り付けることも可能であるし、建物20の屋根の上に設置される足場に設置することも可能である。また、図面上は全て縦支柱の最上段に設けられた受け部を利用して取り付けられているが、途中の受け部を利用して取り付けることも可能である。   By such a procedure, for example, as shown in FIG. 6, the scaffold roof structure 100 is installed on the wedge-shaped scaffold 1. As illustrated, it can be attached to a scaffold installed on the ground, or can be installed on a scaffold installed on the roof of the building 20. Further, in the drawings, all are attached using a receiving portion provided at the uppermost stage of the vertical column, but it is also possible to attach using a receiving portion in the middle.

更に、本発明のクサビ式屋根構造100は、図7に示しているように、屋根構造100全体を傾斜させて設置することも可能となる。即ち、縦支柱2毎に異なる高さの受け部3を利用することで、従来実現できなかった設置を可能としている。   Furthermore, the wedge-shaped roof structure 100 of the present invention can be installed with the entire roof structure 100 inclined as shown in FIG. That is, by using the receiving portions 3 having different heights for each vertical support 2, installation that has not been realized in the past can be realized.

なお、取り外す際は、シート部材120を取り外した上で、クサビ部111の下端をハンマー等で叩き上げることによって容易に取り外すことが可能である。   In addition, when removing, after removing the sheet | seat member 120, it is possible to remove easily by hitting the lower end of the wedge part 111 with a hammer.

このように本願発明は、クサビ式足場1を構成する縦支柱2に設けられる受け部3に嵌入するクサビ部111と、当該クサビ部111を受け部3に嵌入すると水平方向若しくは斜め下方向若しくは斜め上方向に延在する骨部112と、この骨部112の基端近傍及び先端近傍の両側面に設けられた締結部115、116を備えるフレーム部材110と、四隅に穴122を備えた矩形のシート部材120と、を備え、少なくとも2つのフレーム部材110をクサビ式足場1における使用されていない受け部3に嵌入させ、シート部材120の穴122とフレーム部材110の締結部115、116とを紐等の締結部材で締結することによって、フレーム部材110同士をシート部材120で繋いで構成されている。   As described above, the present invention has a wedge part 111 fitted into the receiving part 3 provided in the vertical support 2 constituting the wedge type scaffold 1 and a horizontal direction, a diagonally downward direction or a diagonal direction when the wedge part 111 is fitted into the receiving part 3. A frame portion 110 having a bone portion 112 extending upward, fastening portions 115 and 116 provided on both side surfaces near the proximal end and near the distal end of the bone portion 112, and a rectangular shape having holes 122 at four corners. A seat member 120, and at least two frame members 110 are fitted into unused receiving portions 3 in the wedge-shaped scaffold 1, and the holes 122 of the seat member 120 and the fastening portions 115 and 116 of the frame member 110 are tied together. The frame members 110 are connected to each other by the sheet member 120 by fastening with a fastening member such as the like.

このような構成を採用したことによって、足場の最上段に限らず容易に設置でき、更には取り外しも容易となっている。足場の組み付けと同様に、クサビを打ち込むようにしてフレーム部材110を取り付けるので、取り付け作業は極めて容易であるし、取り外しも容易となる。更に、空いている受け部3に自由に取り付けできるため、最上段に限らず、中段部や下段部においても問題なく設置可能である。場合によっては、低い位置から高い位位置に向かって斜め方向に屋根を設置することも可能となる。   By adopting such a configuration, it can be easily installed without being limited to the uppermost stage of the scaffold, and can be easily removed. As with the assembly of the scaffold, the frame member 110 is attached by driving in a wedge, so that the attachment work is extremely easy and the attachment is easy. Furthermore, since it can be freely attached to the vacant receiving part 3, it can be installed without any problems not only in the uppermost stage but also in the middle or lower part. In some cases, it is possible to install a roof in an oblique direction from a low position to a high position.

また、骨部113は、基端側を中心として、先端部が上下に変位するように回動可能に支持すると共に、所望の角度で固定することができるようになっていた。これにより、状況に合わせて屋根の角度を所望の角度に調整することができる。更に、好天時には、屋根を上部に解放することも可能なため、屋根を取り付けた後であっても、積極的に光を取り入れることも可能となっている。   In addition, the bone portion 113 is pivotally supported so that the distal end portion is displaced up and down around the base end side, and can be fixed at a desired angle. Thereby, the angle of a roof can be adjusted to a desired angle according to a situation. Furthermore, since it is possible to release the roof to the upper part in good weather, it is possible to actively take in light even after the roof is attached.

また、フレーム部材110の右側に配置されるシート部材120は、フレーム部材110の左側面に設けられた締結部と締結され、フレーム部材110の左側に配置されるシート部材120は、フレーム部材110の右側面に設けられた締結部と締結されていた。このようにフレーム部材110とシート部材120とを締結することによって、極めて簡易な構成ではあるものの、シート部材120同士の間に隙間が生じることを防止できるので、雨が隙間から漏れ難くなっている。   The sheet member 120 disposed on the right side of the frame member 110 is fastened to a fastening portion provided on the left side surface of the frame member 110, and the sheet member 120 disposed on the left side of the frame member 110 is It was fastened with the fastening part provided on the right side. By fastening the frame member 110 and the sheet member 120 in this manner, it is possible to prevent a gap from being generated between the sheet members 120 although it is an extremely simple configuration, so that it is difficult for rain to leak from the gap. .

〈その他の構成例〉
上記では、フレーム部材110における棒状部材113が、上下に回動する(変位する)構成とされていたが、所定の角度で固定されていてもよい。
<Other configuration examples>
In the above description, the rod-shaped member 113 in the frame member 110 is configured to rotate (displace) up and down, but may be fixed at a predetermined angle.

また、上記では、棒状部材113の角度調整が、5段階(ピン孔117の穴の位置が5つ)とされていたがこれに限らないし、当然であるが、無段階で調整できる機構を採用してもよい。   Further, in the above, the angle adjustment of the rod-shaped member 113 has been made in five steps (the pin hole 117 has five hole positions), but this is not limited to this, and a mechanism that can be adjusted steplessly is adopted.
